Abstract:
As a help of the relationship between bipolar disorder and alcoholism, we studied the relationship between GSK-3 beta -50T/C polymorphism, which is reported to the relationship for bipolar disorder, and Japanese alcoholics. And we investigated the relationship between GSK-3 beta -50T/C polymorphism and DBI +529A/T polymorphisms, which is reported to one of the risk factor for alcoholism. We analyzed the GSK-3 beta genotype using a polymerase chain reaction (PCR), and DBI genotype using PCR with confronting two-pair novel primers (PCR-CTPP) in 75 health controls and 64 alcoholics. In this study, there was no significant difference in the frequency of GSK-3 beta -50T/C polymorphism between alcoholics and controls (p = 0.883), and there was no significant difference in the frequency of DBI +529A/T polymorphism (p = 0.131). Also, there was no relationship between GSK-3 beta -50T/C polymorphism and DBI +529A/T allele in alcoholism (p = 0.907). We suggested that bipolar disorder may not be one of the pathogenesis of alcoholism, and that there was no relationship between GSK-3 beta -50T/C polymorphism and DBI +529A/T polymorphism.
